Description
- The present invention relates to a multi-zone detergent unit-dose detergent product.
- Detergent formats are known in the art. They are typically configured to provide a stable format which is able to release active ingredients to the washing environment. Generally detergents are in the form of powders or liquids.
- More preferred formats include mono-dose, wherein an amount of detergent is somehow organised for a consumer to use without weighing / measuring and loose materials. For example, detergents may be in the form of a compressed powder body.
-
US2003/045411 describes a water soluble single-use package for detergent or personal care composition. - In recent years it has become desirable that detergents contain a number of active ingredients in order to provide numerous detergent benefits brought about by individual active components.
- Formulating and processing detergents unit dose detergent bodies with multiple active ingredients can lead to problems due to the physical and/or chemical incompatibility of such ingredients.
- For example, it has become commonplace for detergents to contain a halogen release agent or other bleaching agent. Such materials are powerful chemically reactive species, which are difficult to combine with other oxidation sensitive components (such as enzymes, perfumes). Whilst it is straightforward to come up with a format that can accommodate such antagonistic ingredients in a solid form it has been found to be difficult to devise a stable format for any other physical form.
- It is an object of the present invention to obviate or mitigate one or more of the problems outlined above.
- According to a first aspect of the invention there is provided a multi-zone detergent unit-dose detergent product, wherein each zone comprises a gel formulation, wherein the gel comprises a polysaccharide, a polyamide and / or a silica based gelling aid.
- With products in accordance with the invention it has been found that antagonistic ingredients can be accommodated in a non-solid stable format, which, additionally has especially pleasing aesthetic properties.
- Ideally the gelling aid is capable of forming a gel which is soluble / dispersible in an aqueous medium. Preferably the gelling aid is capable of forming at gel at a pH which is largely neutral (e.g. between pH 4 - 10). Preferred examples of such gelling aids include gellan gums (polysaccharide), fumed silicas (silica), high molecular weight esters and / or modified vegetable triglycerides.
- Preferably a single gelling aid is employed for a single zone of the product.
- Polysaccharide gelling aids have been found to be particularly beneficial in stabilising gels (especially gels with a high water content such as >30wt%) which are then packaged in a water soluble / dispersible material. Where a polysaccharide is used as a gelling it is preferably present in an amount of 0.25-4wt% of that zone. An inorganic salt may be used to enhance the gelling ability of the gelling aid. Preferred examples of such salts include magnesium and calcium salts, e.g. the sulphate and / or chloride thereof.
- Silica gelling aids have been found to be particularly beneficial in stabilising gels containing bleaching agents (i.e. the bleaching agents such as per-salts have been found to be stable in gels gelled by silica gelling aids). Additionally / alternatively silica gelling aids have been found to be advantageous since the formation of gels with suitable aesthesis properties such as transparent / translucent gels.
- Where a silica is used as a gelling it is preferably present in an amount of 2-15wt% of that zone, more preferably 4-10wt% of that zone.
- The silica is preferably used as a gelling aid for a zone wherein an aggressive agent (e.g. such as a bleaching agent is present) which could detrimentally interact with a polysaccharide.
- Where a polyamide is used as a gelling it is preferably present in an amount of 2-12wt% of that zone.
- A zone may be water free. Alternatively a zone may contain water. Where water is present preferably the water content of a zone is from 0.1 to 90wt%, more preferably from 10wt% to 80wt%, more preferably from 20wt% to 70wt%, more preferably from 25 to 50wt%, and most preferably from 30 to 40wt%.
- Preferably the product comprises two or more, such as three or four separate zones. It will be appreciated the two zones may be spatially arranged in any suitable fashion. Preferably the zones are arranged in a concentric fashion, e.g. wherein a first zone is enveloped by a second zone. Generally both zones are based on a spheroid shape. Preferably the outmost zone is translucent so that the inner zone may be seen. The inner zone may have a different colouring from the / an outer zone. Where there are two zones, preferably the inner zone is smaller in size than the outer zone.
- Where two (or more) zones are present the separate zones may be used to house antagonistic components (e.g. bleach in a first zone and enzyme in a second zone). Additionally and / or alternatively the zone may be used (since in a preferred arrangement the zones are arranged concentrically) so that the timing of the release of actives from zones may be delayed relative to a second zone.
- A border may be provided between two zones or on the outermost surface of the product adjacent. The border is preferably free of active detersive components. The border preferably has a low water content (e.g. <50wt% water). The border is preferably structurally compatible with the neighbouring zone or zones. The border preferably comprises one or more of PVOH, silica or Crothix (a high molecular weight ester and modified vegetable triglyceride).
- Examples of bleaches that may be used are oxygen / peroxygen bleaches.
- Peroxygen bleaching actives are: perborates, peroxides, peroxyhydrates, persulfates. A preferred compound is sodium percarbonate and especially the coated grades that have better stability. The percarbonate can be coated with silicates, borates, waxes, sodium sulfate, sodium carbonate and surfactants solid at room temperature. Hydrogen peroxide may be used.
- Optionally, the product may comprise a bleach precursor. Suitable bleach precursors are peracid precursors, i.e. compounds that upon reaction with hydrogen peroxide product peroxyacids. Examples of peracid precursors suitable for use can be found among the classes of anhydrides, amides, imides and esters such as acetyl triethyl citrate (ATC), tetra acetyl ethylene diamine (TAED), succinic or maleic anhydrides.
- Suitable surfactants that may be employed include anionic or nonionic surfactants or mixture thereof. The nonionic surfactant is preferably a surfactant having a formula RO(CH2CH2O)nH wherein R is a mixture of linear, even carbon-number hydrocarbon chains ranging from C12H25 to C16H33 and n represents the number of repeating units and is a number of from about 1 to about 12. Examples of other non-ionic surfactants include higher aliphatic primary alcohol containing about twelve to about 16 carbon atoms which are condensed with about three to thirteen moles of ethylene oxide per mole of alcohol (i.e. equivalents).
- Other examples of nonionic surfactants include primary alcohol ethoxylates (available under the Neodol tradename from Shell Co.), such as C11 alkanol condensed with 9 equivalents of ethylene oxide (Neodol 1-9), C12-13 alkanol condensed with 6.5 equivalents ethylene oxide (Neodol 23-6.5), C12-13 alkanol with 9 equivalents of ethylene oxide (Neodol 23-9), C12-15 alkanol condensed with 7 or 3 equivalents ethylene oxide (Neodol 25-7 or Neodol 25-3), C14-15 alkanol condensed with 13 equivalents ethylene oxide (Neodol 45-13), C9-11 linear ethoxylated alcohol, averaging 2.5 moles of ethylene oxide per mole of alcohol (Neodol 91-2.5), and the like.
- Other examples of nonionic surfactants suitable for use include ethylene oxide condensate products of secondary aliphatic alcohols containing 11 to 18 carbon atoms in a straight or branched chain configuration condensed with 5 to 30 equivalents of ethylene oxide. Examples of commercially available non-ionic detergents of the foregoing type are C11-15 secondary alkanol condensed with either 9 equivalents of ethylene oxide (Tergitol 15-S-9) or 12 equivalents of ethylene oxide (Tergitol 15-S-12) marketed by Union Carbide, a subsidiary of Dow Chemical.
- Octylphenoxy polyethoxyethanol type nonionic surfactants, for example, Triton X-100, as well as amine oxides can also be used as a nonionic surfactant.
- Other examples of linear primary alcohol ethoxylates are available under the Tomadol tradename such as, for example, Tomadol 1-7, a C11 linear primary alcohol ethoxylate with 7 equivalents EO; Tomadol 25-7, a C12-15 linear primary alcohol ethoxylate with 7 equivalents EO; Tomadol 45-7, a C14-15 linear primary alcohol ethoxylate with 7 equivalents EO; and Tomadol 91-6, a C9-11 linear alcohol ethoxylate with 6 equivalents EO.
- Other nonionic surfactants are amine oxides, alkyl amide oxide surfactants.
- Preferred anionic surfactants are frequently provided as alkali metal salts, ammonium salts, amine salts, aminoalcohol salts or magnesium salts. Contemplated as useful are one or more sulfate or sulfonate compounds including: alkyl benzene sulfates, alkyl sulfates, alkyl ether sulfates, alkylamidoether sulfates, alkylaryl polyether sulfates, monoglyceride sulfates, alkylsulfonates, alkylamide sulfonates, alkylarylsulfonates, olefinsulfonates, paraffin sulfonates, alkyl sulfosuccinates, alkyl ether sulfosuccinates, alkylamide sulfosuccinates, alkyl sulfosuccinamate, alkyl sulfoacetates, alkyl phosphates, alkyl ether phosphates, acyl sarconsinates, acyl isethionates, and N-acyl taurates. Generally, the alkyl or acyl radical in these various compounds comprise a carbon chain containing 12 to 20 carbon atoms.
- Other surfactants which may be used are alkyl naphthalene sulfonates and oleoyl sarcosinates and mixtures thereof.
- Any suitable soil catcher may be employed. Unlike detergents or surfactants, which simply aid in the removal of soils from surfaces, the soil catcher actively binds to the soil allowing it to be removed from the surface of the laundry. Once bound, the soil is less likely to be able to redeposit onto the surface of the laundry. Preferred soil catchers have a high affinity to both oily and water-soluble soil. Preferably, the soil catcher is a mixture of two or more soil catchers, each soil catcher may have a different affinity for different soils. Preferred soil catchers for oily soils have a non polar structure with high absorption capability. Preferred water based soil catchers are generally charged and have a high surface area in order to attract the soil by electrostatic charge and collect it. Suitable soil catchers include polymers, such as acrylic polymers, polyesters and polyvinylpyrrolidone (PVP). The polymers may be crosslinked, examples of which include crosslinked acrylic polymers and crosslinked PVP. Super absorbing polymers are mainly acrylic polymers and they are useful for the scope of this patent.
- Other important polymers are ethylidene norbene polymers, ethylidene norbene/ethylene copolymers, ethylidene norbene/propylene/ethylidene ter-polymers. Inorganic materials may also be employed. Examples include zeolites, talc, bentonites and active carbon. The latter may be used to absorb and/or degrade coloured parts of stain and/or absorb odours. Alginates, carrageneans and chitosan may also be used. Preferred water insoluble agents are selected from at least one of acrylic polymer, polyester, polyvinylpyrrolidone (PVP), silica, silicate, zeolite, talc, bentonites, active carbon, alginates, carrageneans, ethylidene mor-bene/propylene/ethylidene ter-polymers and chitosanl.
- Preferred examples of water-insoluble soil catcher compounds comprise a solid cross-linked polyvinyl N-oxide, or chitosan product or ethylidene norbene/propylene/ethylidene ter-polymers or blend of the same, as discussed more fully hereafter.
- Water soluble polymeric soil catcher agents that are suitable to be bound to insoluble carriers, or to be made insoluble via cross-linking are those polymers known in the art to inhibit the transfer of dyes from coloured fabrics onto fabrics washed therewith. These polymers have the ability to complex or adsorb the fugitive dyes washed out of dyed fabrics before the dyes have the opportunity to become attached to other articles in the wash. Especially suitable polymeric soil catcher agents are polyamine N-oxide polymers, polymers and copolymers of N-vinylpyrrolidone and N-vinylimidazole, vinyloxazolidones, vinylpyridine, vinylpyridine N-oxide, other vinylpyridine derivatives or mixtures thereof.
- The product advantageously additionally comprises cleaning agents selected from the group consisting of, fillers, builders, chelating agents, activators, fragrances, enzymes or a mixture thereof. These active agents are generally water soluble, so dissolve during the wash. Thus the additional active agents are released over a period of time when exposed to water in the laundry washing machine.
- Suitable fillers include bicarbonates and carbonates of metals, such as alkali metals and alkaline earth metals. Examples include sodium carbonate, sodium bicarbonate, calcium carbonate, calcium bicarbonate, magnesium carbonate, magnesium bicarbonate and sesqui-carbonates of sodium, calcium and/or magnesium. Other examples include metal carboxy glycine and metal glycine carbonate. Chlorides, such as sodium chloride; citrates; and sulfates, such as sodium sulfate, calcium sulfate and magnesium sulfate, may also be employed.
- The product may comprise at least one builder or a combination of them. Builders may be used as chelating agents for metals, as anti-redeposition agents and/or as alkalis.

- According to a second aspect of the invention there is provided a method of producing the product of the first aspect of the invention.
- One preferred method of production is that of extrusion / co-extrusion. In the co-extrusion method the materials for making up the zone are fed into and then simultaneously extruded through a concentric arrangement of tubes. At the exit point of the tubes an amount of co extruded material is collected (an amount of co extruded material may be separated from the extrudate, e.g. by cutting). Surprisingly it has been found that when co-extrusion is used as a production technique the outer zone(s) of the product coalesce over the inner zone(s) of the product forming a product having a concentric arrangement.

- Another preferred method of production is that of sequential moulding. In this method preferably the following process steps are involved:-
- a) A first zone is formed in a first mould,
- b) The first zone is allowed / encouraged to at least partially solid,
- c) The first zone is removed from the first mould,
- d) The first zone s disposed into a second mould,
- e) The formulation of a second zone is added to the second mould,
- f) The formulation of the second zone is allowed / encouraged to at least partially solid, and
- g) The finished product is removed form the second mould.
- Clearly more than two zones may be moulded in this process if more moulding steps are used. Intermediate / final non-moulding steps, such as spraying and / or dipping are not precluded.
- Preferably the first zone is suspended in the second mould so that it does not contact a surface of the second mould. Generally the meads used for this suspension comprise a pin / rod. The pin / rod may be inserted into the first zone at or after the removal of the first zone from the first mould. The pin / rod may remain inserted in the first zone throughout any subject moulding steps. The pin / rod may be used as an aid to finished product is removed form the final mould.
- Each of these processes is preferably automated.
- Following production the product may be wrapped in a packaging material. The packaging material may be in the form of a film. The film may comprise a water soluble component, e.g. be based on polyvinyl alcohol. In this way the product may be used without the need for unwrapping.
- In one embodiment each zone of the product has a film (e.g. an outer film) of a packaging material.
